SLIDING DOOR OR SASH.

Patented Feb. 25, 1908.

Application filed September 19 1906. Serial No. 335.327.

To all whom it may concern:

Be it known that I, GEORGE P. BALOH, of Lynn, in the county of Essex andState of Massachusetts, a citizen of the United States, have invented anew and useful Improvement in Sliding Doors or Sashes, of which thefollowing is a specification.

My invention relates essentially to an improved means by which doors orsashes which lie when closed in the same plane may be made to slide byone another when said doors or sashes are opened, the object of myinvention being to provide a simple means by which one door or sash maybe brought forward and slid by the other door or sash adjacent to it.

I have shown in the drawings my invention as embodied in a simple formof case or closet in which Figure 1 shows the case in front elevationwith the doors or sashes closed. Fig. 2 shows the same with one of thesashes open. Fig. 3 is a cross section taken on the line 33 of Fig. 2,and Fig. 4 is a section taken on the line 44 of Fig. 2.

Referring to the drawings :A represents the case.

a is the base of the case, a a the sides, and a the head.

B, B are the respective doors or sashes closing in front of the case. InFig. 1 the doors or sashes are shown in a closed position, the essentialfeature to be noted being that when thus closed they lie in one plane,or, in other words, their faces are flush with one another.

With reference now to the means for accomplishing the sliding openingand closing of the doors or sashes there is first to be noted the boardsor plates a, a at the ends thereof. In the case shown the board or platea at the bottom of the doors or sashes and upon which they rest is builton to the base portion a of the case while the board or plate a at thetop of the doors or sashes is supported by the sides of the case andsurmounted by the head (1 These boards or plates act as a slotted framebetween which the doors or sashes are contained, and it is by means ofslots or ways formed in this frame in which run pins 5, b affixed to andextending from the respective ends of the doors or sashes that theiropening or closing is accomplished. These slots or ways which are cut inthe plates or boards c of, or frame containing the doors or sashes aresubstantially alike in their formation or arrangement for both boards orplates as may be seen by reference to Figs. 3 and 4. Each board or platehas in it a slot a which extends in front of and by the plane occupiedby the doors or sashes when in a closed osition. Offset from this slotat either en thereof and extending outwardly in reverse directionstowards the outer stiles of the doors or sashes are inclined slots (17,a], or those having an obtuse angular relationship to the slots (1, andwhich slots at, a are inclined back to extend into the plane occupied bythe doors or sashes when closed. I prefer that these inclined slotsshall enter the plane occupied by the doors or sashes when closed at apoint in or relatively near the plane occupied by the outer stiles ofthe doors or sashes when closed as aforesaid. There are also offset fromeach of the slots a at right angles thereto the slots or ways a (i Theseslots like the inclined slots a (1 extend to and into the plane occupiedby the doors or sashes when closed. I prefer also that they shall enterthe plane occupied by the doors or sashes when closed at a point as nearthe inner stiles of the doors or sashes when closed as possible, at thesame time so far removed therefrom or from the inner edge of the sashthat the pins which are adapted to be. contained in these slots will notinterfere with the proper opening of the doors or sashes as will behereinafter explained.

Now'the disposition of the pins 1), b affixed to and extending from thedoors or sashes are such relatively to the offset slots or ways beforementioned that the pins will be contained therein when the doors orsashes are in a closed position. Upon grasping one door or sash or theother at the point of its inner stile, which may be done by a fingerreceiving slot b cut in the edge of the stile (see Fig. l), the innerportion of the door or sash may be drawn out in the direction of themain slots a so as to avoid an abutting edge as that of the other dooror sash. This operation is ermitted because the pins 6 at the ends of te doors or sashes contained in the perpendicular offset slots or ways awill slip directly into the main slots a. The door or sash may then bedrawn to the right or left, depending upon the door or sash drawn out,and made to slide by the other door or sash, the pins 7) at the ends ofthe door or sash running in the main slots of and the pins I) beinggradually drawn out into thesame from the inclined slots a in which theyare contained when both pins will run in the main slots and the door orsash drawn to a fully open position.

The closing of the door or sash is accomplished simply by a reversemovement. The pins 5 on the ends of the doors or sashes will '1rst enterthe inclined slots or ways a which will direct the outer portion of thedoor or sash into a proper closed position, then by pressing inwardlythe forward portion of the door or sash it also will be made to properlyclose, the pins b atthe ends of the door or sash entering the offsetslots or ways a in which they are adapted to be contained.

As may be seen by reference to Fig. 2 the doors or sashes close againsta series of flange forming strips or backing C fixed to the inside ofthe case around the edges of the doors or sashes when in a closedposition. For the purpose of keeping the doors or sashes closed in aposition snug up against the strips or backing before mentioned, I havearranged upon the outside of the respective I boards or plates a aholding devices or boards aforesaid.

springs comprising bent pieces of wire D which engage with the pins 6fixed to the doors and projecting through the slots in the These wiresare held in a normally engaging position by means of pins (Z driven intothe boards a and a and the wires are arranged to yield to the pins asthey enter the offset slots or ways and to yieldingly bear against saidpins when the doors or sashes are closed, thereby holding them closedunder tension. The opening of the doors or sashes is accomplished asbefore explained against the yielding tensional resistance of theholding wires.

The manner of closing the sashes and holding them closed make thempractically dust proof for every part of the door or sash is held snugup against the strip or backing against which it is adapted to bear whenclosed.

For the purpose of making the doors and sashes even more secure againstdust I prefer to cover the strips or backing, and also the edges of thedoors or sashes with felt c, or some other fibrous dust excludingmaterial.

What I claim as my invention is 1. The combination with doors or sashesflush with one another when in a closed posiends of said doors or sashesand contained in slots or ways formed in said frame, said slotscomprising main slots or ways formed in said frame at opposite ends ofthe doors or sashes extending on lines outside the plane occupied by thedoors or sashes when closed and parallelly therewith and slots offsettherefrom arranged whereby the inside portions of eitherofsaid doors orsashes may be moved in the direction of said main slots to avoid anabutting edge, and said door or sash have clearance to slide in saidmain slot by the members affixed thereto.

2. The combination of doors or sashes flush with one another when in aclosed position, of a frame between which the doors or sashes areinterposed, members affixed to the ends of the doors or sashes andcontained to run in slots or ways a, a and a formed in said frame, saidslots a comprising slots formed in. said frame at the opposite ends ofthe doors or sashes and extending on lines outside the plane of saiddoors or sashes when closed and parallelly therewith, said slots ccomprising slots perpendicularly offset from the main slots a, and theslots (i comprising slots ofiset at an angular inclination with respectthereto and in which offset slots a a the members affixed to the doorsor sashes are adapted to be contained when the sashes are in a closedposition.

3. The combination with doors or sashes flush with one another when in aclosed posi tion, of a frame between which the sashes are interposed,slots or ways formed in saidposition or be drawn forward to slide by oneanother, and yielding members affixed to said frame between which thedoors or sashes are interposed for holding said'doors or sashes in aclosed position.
